I thought I post it here instead of creating new thread as it deals with a similar problem.. The bottom part of the shirt (the 'skirt' part) doesn't smooth properly when using subdiv proxy. It looks good in the preview, but once I do the actual subdivision it keeps the original hard edges. The edges around the 'skirt' can't be changed to soft edges for some reason. The skirt was created by taking an edge of the body and extruding it outward.. Do you guys have any idea what's wrong with the mesh? (p.s.: I checked the normals and they're all correct)
